1910, and I know I've posted about it years ago, but can't find the info,.... it's a custom coachbuilt body over a Rolls chassis if I recall correctly, funky looking.
1918 policeman in San Diego
this 1929 BMW R11 was available with the Royal sidecar
looking like a tank, built over a Tucker sno cat ... my guess is for "burning man"
and lastly two cars built to look like trains. They were great advertising vehicles, mostly used by movie companies to get an audience for the theaters, but the above is advertising tires and the below is lettered with American Legion, Miami Beach to Boston... maybe to sell war bonds?
Lots of great cars, trucks, trains and bikes at http://steampunkvehicles.tumblr.com/
